According to a Turkish legend, there was once a massive rock by the sea, which even the force of a thousand men and a load of dynamite couldn't move or crack. There was also a man in the town, known to carry the evil eye (nazar). After much persuasion he was convinced to come to the rock. He took one look at it and said, "My! What a huge rock". No sooner had he uttered the words than there was a rip, roar and crack and the impossible boulder split into two. Indeed, the deep-seated fear of the harmful eye has meant that wearing a rival eye - a protective symbol that can outstare the evil one - has proved immensely popular over many centuries. One such object is the blue eye from Turkey, known locally as nazar boncuk, which is set into a variety of jewelry forms.
